Ros?

Harry's told Bakhshi.

We've agreed to let him prepare his own cover story.

Fine.

Ros, I should never have put you in that position, or Ana.

We all cross boundaries.

It goes with the territory.

I probably said a lot of strange things last night.

But if one of them was "thanks", I meant it.

Iran is joining the atomic club.

The Home Secretary will need reliable intelligence.

We know the Iranians are racing

to enable triggers for the missiles they've already bought,

not least because they're surrounded

by US carriers in the Gulf.

Harry, I--

But the blueprints we intercepted were useless fakes.

Our asset has just confirmed

Iran has sourced working circuit boards,

plug and play.

A fully-armed nuclear adversary.

This source of yours, did he give us anything else?

She! Ana Bakhshi.

Wife of the Iranian Special Consul.

She won't be giving us anything now.

Ana died last night

whilst trying to kill one of my officers.

Adam Carter, her handler.

Cloak and dagger, Harry?

Honey traps?

Did nobody tip you off the Berlin Wall came down yet?

Six we're hearing nothing on the ground in Tehran.

Ana gave us everything. - And the rest.

While Adam was gazing in her eyes,

she slipped something in his drink and left him to die.

Not my idea of foreplay.

She told us the real circuit boards fly today from London.

Today?

They must have known the blueprints were a decoy.

Is Bob right, Harry?

Is the leak on our side?

Do I have to ask you to search the Grid?

My agency is requesting guarantees

you'll ground all flights to Tehran

to ensure those triggers don't leave the UK.

I trust Section D are already one step ahead

and will be co-operating with our American friends.

Gentlemen.

So three airlines leave for Tehran today,

Persepolis Charter 14:30,

British Intercontinental 15:05,

DLG 16:50 with a stop in Frankfurt.

Where's Bakhshi's brother?

If he was sent to collect the doctored blueprints,

then he must be first in line for the real set.

We've been all over him since the handover.

If he bought so much as a packet of crisps, we'd know it.

They must be using a new courier.

Spoiling for a fight, Harry?

If Iran goes nuclear, Israel will escalate the stand-off

and America will be forced into a pre-emptive strike.

Not even Hogan dares risk that.

By the way, the Joint Intelligence Committee

seem to think that we here in Section D have a mole.

They'll be conducting a full sweep of the Grid.

By the way, the Joint Intelligence Committee

seem to think that we here in Section D have a mole.

Connie, get me the head of the Airports Authority.

We let everyone board then hold the flights on the ground

until we find our target.

I wouldn't do that, Harry.

We've just received an anonymous e-mail.

50 liters of dimethylmercury

are waiting to be released in your water supply.

Unless the courier with the circuit boards

reaches Tehran safely

we will activate the device.

Any attempt to disarm it will be monitored.

Nobody outside this room apart from Rolfe and Hogan knows

we know about the circuit boards.

50 liters.

That's enough to take out an entire city.

Whoever the poisoner is, he knows what he's doing.

He also knows what we're doing.

We can't confront the courier

smuggling the circuit boards

or he'll send a panic signal to release the poison.

We let all aircraft take off as usual,

but we track everyone flying to Tehran

while we locate and neutralize the poison.

Malcolm, what do we have?

Colorless liquid neurotoxin.

A gram is enough to kill a million people.

The last scientist who studied it

spilled a drop on her protective glove.

Within 15 seconds,

it had penetrated the latex and reached the skin.

Once it had crossed the blood-brain barrier,

she began to suffer from ataxia,

sensory disturbance, blurred vision.

They found 80 times the toxic levels in her bloodstream.

She never came out of the coma.

Over 100 pumping stations alone feed London.

If they're monitoring the target,

then we can't involve the police.

Assuming we can find it, can we contain the contamination?

If it's in a single location and if it's a closed system.

And if not?

Hundreds of reservoirs.

A single bird-watcher could tip

a thermos of cyanide into one.

No-one would notice for days.

There are 10,000 miles of mains in London alone.

248 people on three aircraft,

and the first flight leaves in three hours.

Connie, you know how to charm Six.

I'll hit Interpol, okay?

Red flags, recent movements

and unusual financial transactions?

Harry?

Harry, if Ana did know about the real circuit board,

she could only have found out from her husband.

You seduced her, we used her.

Bakhshi feels deceived and betrayed.

I doubt anything he says or thinks right now

will advance our cause.

Before we go after the triggers,

we have to find the mercury ourselves.

Harry Pearce?

I've been instructed by the Home Office to--

Counter surveillance sweep?

Bug extermination?

We've set up a blocking frequency,

so you'll have to patch all mobiles to landlines.

It's all yours.

Right, come on, this way.

You spies, you love your mystery, don't you?

I'm taking a wild guess that Yalta

are behind the real circuit boards.

Oh, you're being too modest.

We couldn't possibly have set this up without you.

Iran could become a nuclear power within 24 hours.

I agreed to help you stabilize international diplomacy,

not fuel war.

Nobody wants that.

Well there are powerful voices in Washington

What did they fear?

Iran's power, they want her resources.

If we help Iran withstand American tyranny,

we can finally break their dominance.

Nagasaki, My Lai, Guantanamo.

What's next, hm?

Harry's having the Grid swept for bugs.

There are two left, one in his office.

If they find them-- - If they find them,

you'll be no more use to us, or to Harry.

Adam's patching through from a secure line.

He says it's urgent.

Where the hell is he?

Sounds like it's a restaurant.

Oh! Well, thanks.

Excuse me?

Can I have a bottle of mineral water, please?

- Sure. - Thank you.

How is Ana?

She has had to return to Tehran.

Her uncle died.

That's Bakhshi, sly as ever.

Who's this?

Why are they speaking Russian?

Something about blueprints.

The, erm, er kooryeram. What's the word?

- Courier. - He's British.

So we know the target.

How many leaving have UK passports?

52.

Come on, Adam!

Very nice of you.

So do you often send champagne to strangers?

Well, it may be the first time.

Really?

Every British passenger on every flight

has been cleared for security.

No red flags.

Is Bakhshi hoping to plant the circuit boards on someone,

an unwitting mule?

He must know we can track them.

He knows we can't do a damn thing

unless we find 50 liters of dimethylmercury.

Okay, this is what Bakhshi says.

That "the Americans sold us doctored blueprints.

"They thought they could force our hand,

"but Iran will make her own moves."

Then Deineko answers, "How did you find out?"

Bakhshi says, "Keep your friends close,

"but your enemies closer."

That's when they laugh.

And he goes on, "We have working circuits now.

"Our man flies today.

"What an irony the courier should be British."

And Deineko replies, "If the Americans challenge you,

"Russia will respond with equal force."

Armageddon.

We are not getting any leads

on the mercury or the passengers.

It's 52 British travelers with no previous security records,

not Six, not CIA, not Interpol or the police.

The Persepolis flight leaves in two hours.

If Bakhshi knows about the circuit boards,

there's no way he doesn't know about the mercury.

I've checked his phone records for the last two weeks.

If he's involved, he's using another handset.

Well then let's get that handset.

- Ow! - I'm sorry.

- Damn! - Are you okay?

Oh. Ah, just twisted my ankle.

I'm terribly sorry.

How's your Russian?

I explicitly forbade you to follow him.

No, you explicitly forbade me not to get caught by him.

Get to the airport now.

It's a British courier.

We need to make sure every damn one of them boards safely.

Then what?

We're working on it.

With three planes and no leads,

it looks like I'll be tossing a coin.

You'd better send me a bag and a passport.

We're tracking a device.

It has to arrive safely.

It's some kind of electronics.

It could be as small as a pack of cards.

Now I don't care if you hear a bag ticking

or see a lit fuse, you just tag it and let it through.

Everything gets on that plane.

This is Jo calling from Section D.

How long before the download's complete?

Progress?

We have to tell Bakhshi the truth about Ana.

What would that gain us right now?

He has the power to stop the triggers and the mercury.

He's in no fit state to decide what he wants.

Harry, please.

We have to tell him she's alive.

We have to make him see sense.

Last night, you fired a shot

to make Adam believe that Ana was dead.

Help him break her spell, you said.

I agreed to hold Ana in a safehouse

until we secured the circuit boards.

That way, Bakhshi would never know

that she'd told us about the real set.

Unless you've got better intelligence,

sounds like a pretty solid plan to me.

Find the poison, Ros.

Bakhshi had a second phone.

We copied the SIM.

Everyone he called in the last 24 hours

and everyone they called.

If he's behind the mercury, our answer's there.

Needles or haystacks?

Better start dialing.

The Persepolis flight leaves in 30 minutes.

Do we let Adam fly until last night?

Did you get any leads from the phone?

We've only just got it!

Then he flies.

And if it's the wrong one, Ros, you take the next.

And if that's the wrong one?

Then my passport's in my desk.

Just a minute.

All remaining passengers flying on

Persepolis Charter flight 772,

the gate is now closing.

Will passenger Tennant

please make his way to Gate 42?

Adam, the Russian word, we were wrong.

It's not "courier", it's "carrier".

It's not a British passport, it's a British flight.

British Intercontinental 1505.

84 passengers.

We'll get you more as soon as we can.

Jo's still working on the water.

You're gonna need some way

to communicate with the planes.

Better get Malcolm to Heathrow.

Okay, we're sending me engineers unit.

Can you have a look to it in the meantime?

Call fix it, sir.

Fine, just get back to the tunnel.

Tell the carrier that the aircraft has failed safety.

Airport security need to know too.

Why?

Sir, the flame arresters has been disabled.

I've got bare wires hanging over 6,000 gallons of Jet-A.

The flame arresters have been smashed.

Both engines.

Can she fly without them?

If she hits turbulence,

there's nothing to protect the fuel vapor.

If she flies through an electrical storm,

she's a sitting duck.

Spare aircraft?

Not unless we delay.

No delay. Bakhshi will know.

He'll release the poison.

Arming Iran?

After everything we've been fighting for?

Just let me find them.

I won't move until I know the poison's safe.

Tell the engineers to report the fault

when the plane returns.

I'm boarding now.

Please don't tell me bringing down that aircraft

in a fireball over Europe was one of your schemes.

We crippled three planes

to keep the circuit boards here, safe.

You're the one condemning 84 passengers

by letting them take off.

That flight leaves on time

or this city faces mass evacuation!

The slightest cock-up causes a delay,

Bakhshi will know we're stalling.

Think global, Harry.

You already lost one empire.

I can't hold.

You need to get your manager on the phone now.

Ros, I've got something.

This is the security service.

We urgently need the name of the person who called you

at 6:54 yesterday evening.

One of Bakhshi's contacts placed an emergency call

to the Health and Safety Office.

Yeah, I'm sending over our access code.

Please just read the call log.

An engineer reported an exposed mains feed,

refused to work until it was made safe.

Electrics?

Where did you say the fault was?

Molden House.

Do you have any idea

what that amount of dimethylmercury could do?

I deliver information, not poison.

Bakhshi is only using the threat

to guarantee the safe arrival of the triggers.

Just tell me who the courier is.

That hardly matters.

If you stop Iran from getting the circuits today,

you know damn well they'll buy them

from someone else tomorrow.

Think big, Ros.

Bigger than Harry, at least.

What I'm doing for you is treason!

Harry knows there's a mole.

Are you afraid of him?

Or are you afraid of a world

where Section D answers to Hogan,

because America rides roughshod over the rest of us?

You still think this is a pissing contest, don't you?

Real people are gonna die today,

people who did not sign up for your grand crusade!

Listen, Malcolm.

The only Paul Laystall who worked for Health and Safety

died two months ago.

Looks like somebody used his ID to get into Molden House.

If they're watching,

I'm gonna need some help getting past their security.

I'm on my way.

Hey, darling. Missing you already.

Everyone's boarded now.

81 are cleared.

They're mostly Iran nationals

plus the usual run of businessmen

and IT warriors and oil jackals.

Three remaining have red flags.

Nicolas Faures, advisor to the French nuclear program

till he was carpeted for taking kickbacks.

Anastasya Poselskaya, ex-FSB, no known employer,

but she's hiding 12 grand a month in cash.

And Ebrahim Jannati, Iranian passport, no available records.

What nothing?

Oh, he's either very clean or very clever.

We're waiting on the seat numbers.

I'm sorry, sir, but all phones must be switched off.

Don't dally, darling.

I'll be in the air before you know it.

All the baggage in the hold has been passed,

searched and X-rayed.

If the circuit boards are on that flight,

they're in there with you.

Is the water still shut off?

I hate to leave you without sorting it all out.

Jo's on her way.

Harry says under no circumstances

are you to make a move until she's clear.

We know where the mercury is.

Just sit tight, Adam.

Promise to let me know the moment you're safe and sound.

Any message-- - I'll find a way.

We are authorized to remove personal equipment.

if passengers contravene the safety regulations.

I'll call you as soon as I get the seating plan.

Good luck, darling.

Excuse me, sir, could I just...

All bags must be stowed for take-off.

Please give me the bag, sir

I will stow it for you.

Are security still on the jet way?

Excuse me, he's just worried about his bag.

Could you please sit down, sir?

We will take care of this.

This person's phone is switched off.

Please try again later.

British Intercontinental 434 cleared for take-off.

Cleared for take-off, British Intercontinental 434.

Adam's in the air, waiting on our all-clear.

We can't contact the control room,

whoever set the mercury will be watching it.

There's a loading bay round the back.

All right, now go quietly.

The whole plant may be bugged.

Ladies and gentlemen,

this is the captain speaking.

We are now cruising at 41,000 feet.

The weather ahead looks good

and we should be making an on-time arrival at Imam Khomeini.

We are currently just crossing over the Channel

and the cabin crew will be serving drinks shortly.

I do hope you relax, sit back and enjoy the flight.

Would you like red or white with your meal, sir?

I'd stick to water.

Very dehydrating, all this flying.

I'm expecting a message from the cockpit.

Our ground staff patched a private channel

to the handset in the rear galley.

No news yet.

In case things get bumpy.

Bag...

Sorry. I'm just looking for a pen.

I know it's here somewhere.

Careful. Someone's been here.

There could be a trip wire.

Could be a contact, magnet or a metal strip.

I've got it.

Must be a cut-out.

I'll have to try and short it.

Drop the voltage and easy does it.

Even fingertips can pass current.

I should have been a surgeon.

How we looking?

I'm there. We're home and dry.

It's a trap, it's a trigger!

They must have reversed the switch.

Are you in?

It's here, but they set a trip, a double-bluff.

Has the poison been released?

I don't know.

But something's wrong here, Harry.

Badly wrong.

This is chicken.

I specifically requested a vegetarian meal.

Oh, so sorry, sir.

I'll fetch one in a minute.

It's just gone nuts.

I'm down to three bar on seven and nine.

Emergency services. There's been industrial leak.

Groundwater? What's the hazard code?

What's the alarm?

Pressure failure on two main risers.

In English?

- A feed must have ruptured. - Well, show me.

2.72, 2.88.

Full feed pressure should be five, minimum.

Okay, where are the pipes?

How do we get to them?

This whole building runs 300 feet underground.

We pump water up from the reservoir.

Danger. Contamination alert.

What's the pump output on seven and nine?

900 liters per second.

What kind of poison is it?

We cannot allow any water to reach the mains supply.

There's enough dimethylmercury in the system right now

to kill any person who opens a tap

between Canterbury and Reading.

We need to close down every valve

between here and the mains entry.

What's the diameter? - 60 centimeters.

I could re-route it through the holding tanks.

Or I can loop it round the oxidizers.

A flow speed of just over three meters per second,

350 meters.

We have just under two minutes.

But it all leads to the mains.

I routed it myself. I wrote the software.

You designed an entire pumping station

with no way to shut it down?

We just balance the supply.

We lift it into the system.

You pump it?

Yeah, from the underground repository.

Gravity, man! Where's the mains feed?

Electricity, not water.

- Ah... - Ah, you stupid prick!

I'm so sorry, sorry.

I don't forgive you, asshole.

I don't believe I did that.

I'm such an idiot. I can't believe I did that.

You prick.

- You'll crash the system. - Yeah with any luck.

40 seconds.

Wood, it's a good insulator, right?

None better.

Connie, any news from the pumping station?

Not yet, but we have another problem.

The Met Office says there's a storm building

over southern Turkey and it's pretty severe.

Without those flame arrestors,

a single bolt of lightning could ignite the tanks.

I'm trying to contact Adam.

Everyone we red-flagged is clean.

What do we tell Harry?

We tell him the truth.

There's nothing we can do now till the poison is secure.

It has to be here.

It's two hours until we land.

Between us we've checked all 84 passengers.

- 85. - What? No, absolutely not.

Connie had the manifest.

She confirmed it when we took off.

I counted them three times.

There are 85 passengers on board.

Have you seen the landing cards?

No, sorry, I haven't.

Sorry, not feeling very well.

We can't find the landing cards.

That happened to me last month on the way to Moscow.

We'll have to make a list.

It's falling back to the reservoir.

Is it sealed?

So long as those pumps are dead, it's going nowhere.

Contained, thank God.

Where's the aircraft now?

We need them to turn round right away.

Turkey.

Traffic Control on the line.

I'll tell Adam he can tear that aircraft apart.

He may not need to.

I'm gonna do a little interrogation of my own.

Ladies and gentlemen, I apolo...

Request to collect all your passports now

prior to our arrival in Imam Khomeini.

Four million lives, for a circuit board?

I don't know what you mean.

I serve the wishes of my country.

War?

Is that what your country wishes, Dariush?

Your Government just authorized £70 billion

for a new Trident missile system,

more than my country's entire foreign reserve.

You call it defense.

Why should we not, too?

Ladies and gentlemen,

this is the Captain speaking.

As you may have noticed,

we are experiencing some turbulence at this level.

Unfortunately, we have to remain at this level

till we're outside Eurocontrol and cleared to climb.

So if your own safety, please remain seated

until the seatbelt light switches off.

Shit!

You know that any attempt to arm Iran now

will be seen as provocation.

The stakes are too high.

19C.

How the hell did he get on board

without being listed on the manifest?

At least we found our man.

Don't do anything hasty.

He could still trigger the mercury.

There's nothing from Harry?

Your officer seduced my wife.

He poisoned her loyalty to her country, and to me.

You sent Adam Carter and you knew what he would do,

because you dared not come to me yourself.

Well...

I'm here now.

You can talk to Ana yourself, find out what really happened.

Ana, my love, are you safe?

Darling.

Are you hurt?

I'm okay now.

They wouldn't let me talk to anyone.

30 minutes till we leave European airspace.

I've always wanted to see Tehran.

Preferably not through the bars of an interrogation cell.

Tell us where the circuit boards are hidden

and you can finish the conversation.

I am a diplomat, Harry.

Not a terrorist.

Excuse me, I think they mixed them all up.

Simon Tennant? Sure. I got yours.

Thanks, I hope this isn't a taste of things to come.

I've been told that doing business in Tehran

is a comedy of errors.

Well I'm sure embassies are used

to sorting out this kind of mess.

Have you been there a lot?

Well, I have a colleague who represents my business there.

Listen, I managed to get a room

at The Esteghlal on Pasdaran, but I hear mixed reports.

Do you think I should keep looking around or?

You're not in Kansas any more, Simon.

The Esteghlal is fine.

Ladies and gentlemen,

we are still experiencing considerable turbulence.

Please remain in your seats with your seatbelts fastened

until the seatbelt signs are turned off.

Excuse me.

It's him.

We'll find a way to get the circuit boards

if we don't fall out of the sky first.

I didn't have you down as a nervous flier.

You might be too, if Malcolm had told you

we're sitting over 2,000 gallons of unshielded fuel.

Without the flame arrestors it's not a plane, it's a bomb.

Well, it's certainly one way of dealing with the triggers.

All I know is the triggers fly today

on a British aircraft.

Perhaps they have arrived already.

Perhaps you know more than me.

What do you mean you can't get in touch with the aircraft?

Try the pilot through the emergency channels.

He has to land immediately.

His fuel could blow if he doesn't get out of that storm.

British Intercontinental 434, this is Elazig Tower.

Turn heading 045 degrees.

This will be radar vector for the ILS 23.

Please advise landing.

Connie.

At last! The water's safe.

Do what you have to to get the triggers.

They found it. We're clear.

I need to search your bag.

I'm warning you to sit down!

Put your hands where I can see them!

I'm American.

You've got the wrong guy. - Yeah, right!

You've never been to Tehran.

The Esteghlal is the only hotel

where an American would stay, but it's not on Pasdaran.

Stay down. Stay down.

Stay down.

You all right? - Yeah.

Move.

Move, go to the back of the plane.

Everybody just stay calm.

Just stay calm.

Stay calm, everyone. - Excuse me.

Stay seated.

We'll make sure you're safe.

If they land the plane in Iran they'll lock it down.

Why hasn't Harry authorized the pilot to turn back?

I don't know.

It's got to be in the laptop.

You need to turn this aircraft around.

You'll receive orders from traffic control!

Connie, we have the courier.

His name's Frank Lowell.

You have to authorize the pilot to turn back.

I did. Open channels, emergency codes.

I'll try again.

You must not proceed to Tehran!

Why won't they land?

The crew have orders not divert if they suspect a hijack.

Listen to me!

You have to land this aircraft now!

I am not prepared to negotiate with terrorists.

Everyone back in your seats.

Please stay in your seats.

How long till we cross into Iraq?

Any time now.

Connie's on with Elazig tower.

They've authorized the pilot to turn back.

They'll be entering Iraqi air space in four minutes.

We're about to lose the triggers.

We're not turning.

At least they won't get the triggers.

The flight is refusing to divert.

They're on course for Tehran.

Who's the pilot?

Alan Patrick. I cleared him myself.

At their current speed

they'll enter Iraqi airspace in 90 seconds.

Ros, we have one more chance to get you back.

I need you to get your phone and switch your Bluetooth on.

I want you to text in the following number.

Okay.

Get everybody seated safely.

Everybody, take your seats and fasten your seatbelts.

Fasten your seatbelts.

Could you all fasten your seatbelts?

7-5-7.

You should have five seconds.

Can you all fasten your seatbelts?

Sir, sir, sit down now.

Seat belt on!

I set a charge to take out the fuel pumps.

Well you said we might have to force a landing.

It must have ruptured the fuselage.

The pressure loss won't harm them

if they get down fast enough.

Mayday. Mayday.

This is British Intercontinental 434 initiating descent,

diverting to Elazig Airport for emergency landing.

British Intercontinental 434,

this is Elazig Tower.

We have acknowledged your mayday

and you are cleared center-fix runway 32 at Elazig.

You'll be remaining on my frequency till you're down.

Elazig, NATO base.

Connie, get me the Commander.

I don't want the courier interrogated

by anyone outside Section D.

Do we have a name?

Frank Lowell, traveling as an American.

Told Hogan repeatedly US passports are too easy to fake.

Harry. How's the global village?

We've forced the Tehran flight down at Elazig.

Need my help to clean up the mess?

Your mess.

The courier carrying the circuit boards

was traveling on an American passport.

Frank Lowell.

Harry, Lowell's ours.

We put him on in case, Adam screwed up.

You've got the wrong guy.

Ladies and gentlemen,

we have successfully executed a controlled emergency landing

into Elazig Air Base.

If I can ask you to be patient

whilst we wait for the ground staff to give the all-clear.

Then we can disembark.

Thank you for your co-operation.

Harry. Lowell's dead.

But we destroyed the circuit board.

Lowell's CIA.

The only thing you destroyed

was our relationship with the United States.

I need you to find out why the pilot

disobeyed clear orders to turn back.

Stop the pilot! Stop the pilot!

Search his bag.

I'm a member of the British Security Services!

That man has a trigger for a nuclear warhead in his bag!

I'm with the British Security Services,

my name is Adam Carter.

Your passport says Simon Tennant.

Look, I'm with the British security Services!

Ros!

Ros! The bag!

Ros!

Ros!

Ros, the bag!

They're in the bag!

- Harry. - Ros, it's the pilot.

I have him.

How did Bakhshi get to him?

He has no links to Iran.

No red flags.

We've no idea who he's playing for.

Give me that bag!

Give me the bag!

Miss, get off from the floor.

What are you doing?

Madam, please, give them back to me.

Harry. Harry, he's clean.

It's not here.

Ros, the bag! They're in the bag.

They're in the bag! - Jeep!

The jeep! Stop that jeep!

Stop that jeep!

Ros destroyed two already.

Eight grand each, those transmitters.

I found the last one in Harry Pearce's office.

Does he know?

We can't afford to burn Ros.

Not yet.
